Can you please write a bit more about how, what materials did you use, where did you buy them, how did you soundproof etc. Really interesting topic and I am keenly awaiting your information. Thank you.
In order to soundproof my apartment, I installed double-pane windows. It was quite expensive, as I have very large windows.
In my bedroom, I also have very heavy soundproof curtains, which also really help.
On the 2 wooden doors, I have soundproof blanket on the interior side.
So now my apartment is all covered, and whenever needed I can shut it down completely.
I have a big AC unit in my room, that I mostly use in the "FAN" mode, so power bill isn't too high.
It has been a few months now, and I can tell you, on a personal level that is has been a LIFE-SAVER.
Where I live in Las Terrenas, Capitaleños started showing up since July 1st, renting AirBnBs all the time. Mostly weekends, but also sometimes the whole week too!
And of course, I have been reminded this is THEIR country, that I can go back to my own, & that I am a bigot because I dare say I dislike the obnoxious noise level.
So now, I can stop complaining, I close all my windows, turn on the AC, play a bit of jazz, at a low volume level, and it's like heaven, I don't hear all the "mambo" outside.
Most Gringos in Las Terrenas are facing the same issue. Most I talked to say: "No way, I am not shutting myself down in my house, this would feel like jail!". My answer is that is is FREEDOM for me, as I can't realistically move out of here. I love to read, I work online. I can do those things in silence whenever sh!t hits the fan.
It was expensive, but it's totally worth it.
